Unlucky owner of a Greenwood 100. I have tried to email, but recieved no response from them. Filed a complaint with the Better Business Bureau. So far the BBB has recieved no response from Greenwood after two attempts to contact them. I called a local wood boiler dealer who I bought it from, but no longer carries greenwood and was told they are out of business. This really stinks as this cost me a good chunk of money to purchase and install. I am still recieving emails to buy a Greenwood furnace though, I have recieved two in the past 2 weeks, so I don’t really understand how if they are out of business I am still recieving emails.

I had a model 100 installed last fall. The installation wasn’t the best. I added a draft inducer to the flue that really helped with a bad creosote problem. I saw on their website last year that they have a cleanout kit where you can remove a side panel to gain access to the manifold and air tubes. Part of the kit is extra insulation to enable future cleaning ease, and a special scraper to clean the tubes. There is also a drill mounted cleaning attachment to help. Just tried to call Greenwood Recovery LLC (425)424-4700 and only got the machine. Their 800 number is disconnected. The maniforld is warranted for ten years, but won’t make a difference if they are out of business.

I have my greenwood 100 for 2 1/2 years. It has been nothing but problems. 1 1/2 years in the heat exchanger sprung a leak and had to be replaced. Which I had to do myself, talk about a nightmare, heavy and dirty.This thing builds creosote like you wouldn’t believe. Cleaning the exchanger is also a near impossible chore. I have tried every recimmendation from green wood and it still disappoints me. It leaks smoke from every seam when it is idle. I am ready to remove it, but I have 7 cords of wood ready to go. Wish I went with a Tarm would have cost me the same and had a better product.

I believe they have stopped producing units and are not responding to warranty requests?

Where you happy with your greenwood, I had heard that they were going out of buisness and did not know why so i held off on buying a 300 I was looking at to do my radiant floor and domestic hot water

Also I now note that you say your damper closes at 140. Your aquastat according to the manuel should be set a t 180 max with 15 degree variance so it shuts at 165 degrees. Thus far this seems to work for me. I \tried setting it higher (195) but I am thinking I am just wasting wood. If the furnace will hold at 165 degrees and do what I need it to do then that will be the magic number for me. I would have thought 140 degrees would not give you sufficient heat to keep the 14 rads hot and stay at 140 degrees in the wood unit. I am learning the trick is to keep the wood boiler just idling at 165 to keep my places serviced. The wood boiler will dive down to 150 plus when demand is strong and then shut the damper when the front aquastat reaches 165 degrees. Everyone’s demand is obviously going to be different and by next season I will know what temp I need to keep the wood boiler at to burn the least amount of wood and still keep my places warm and showers hot. 140 degrees seems low……….as 300’s manuel states set the aquastat at 180 thus utilizing the 15 degreee variance (165 for an idle)

I recently installed model 300 and heat 7-unit apartment building and my 3500 sq ft residence. Thus far at 5 to 10 below 0 I am getting from 6 1/2 to 8 hr burn time. My wood is rock maple but is wet as it has been uder snow all winter. I have no problem getting the unti up to temp 165 degrees and damper will shut. I have noted that one must burn wood to get the heat. If wood is almost gone temp starts to come down and after 8 hours I have seen it as low as 130 degrees. I expect next season when I have my wood inside and seasoned better I will have a bit longer burn time. I will also have larger wood – alot of my wood is 3 to 6 inches. I have hot water radiation in the apt building and in-floor in my home. furnace does all my domestic as well. Have had no complaints as far as low heat but have only been running for two weeks. Unit is 150 ft from apt building and 250 from my home.
